(c1. io-7) Onefobject of this invention is the provision of a sign adapted to` display various numbers from to 9, the device being so designed and constructed that by turning a number of handwheels or knobs, any number within the range above-mentioned may be changed toany other number within that range.

Another object of the invention is the provision of such `a device in the form of ar substan.

tially cylindrical upright casing having avertical opening through which the numbers formed are displayed, one at a time.

Still another object of the invention is the provision of a rcylindrical casing as above-mentioned, and a plurality of multilateral' rotatable sections having the edges forming the sides thereof painted or otherwise'marked with sections of the numbers above-mentioned, each section being independently rotatable to bring any of its sides into view in the vertical opening in the cylindrical casing.

The above and other objects willbecome ap-` parent in the description below, in which characters of reference refer to like-named parts in the drawing. f l

Referring briey to the drawing, Figure 1' is a plan View of the device.

Figure 2 is a front elevational view of the same, showing the lvarious rotatable sections aligned to display the number 9l in the casing opening. l l Figure 3 is a cross-sectional view taken on the line 3-3 of Figure 4. i

Figure 4 is a cross-sectional view taken on the line 4-4 of Figure 3. u

Figure 5 is a perspective View of one of the rotatable sections forming the numbers.`

Referring in detail to the drawing, the numeral 10 represents a hollow base upon which the cylindrical casing 11 is mounted, the latter being provided with a vertical opening or window 12. The roof of the hollow base 10, which is also the floor of the cylindrical casing 11, is indicated at 13, and the roof of the casing 11` is indicated at 14. v

The upper surface of the base 10 is provided, within'the enclosure of the casing 11, with a peripheral groove 15. In this groove 15 the depending flange 16 of the lowermost rotatable section 17 rests. In Figure 5 is shown a fivesided section 17, having each of its sides variously marked with fragments of numbers. Each such section is provided with a central circular cut-out provided with peripheral ring gear teeth 19. These sections, except the lowermost (in Figure 4) are identical to eachother, the ring 20 on which the teeth 19 are providedy rising above the surface of the pentagonal section to provide a shoulder, and the pentagonal section about the said ring extending downward below the ring to provide a similarv peripheral shoulder atthe bottom. The lowermost section 17 is similarly designed on its top, but the lower surface diiers as above-mentioned. lIt is thus apparent that all ofthe sections are rotatably interlocked with each other on the same axis,y each being subject, however, to independent rotation as described below. V y

A plurality of spaced-apart vertical shaftsZl is rotatably mounted between the casingfroof 14 and the casing floor 13. Each shaft is provided with a pinion 272each pinion being in` mesh with one of the ringgears 19, there being the same number of shafts and pinionsl as sections. 17. In the hollowvof the base 10, each shaft 22 is provided with a knurled knob 23byk means of which each shaft may be rotated independently.

The. operation of until the desired markings for the proper num? ber arebrought into the window, so that when the sides bearing the desired markings are aligned in the window, the proper number willA be displayed.A

It is to be noted that sections such as shown at 17 having more or less than five sides, mayy be provided, the number of sides being deters mined by the manufacturers. By increasingthe number of sides toy each section',the number of sections lrequired may be reduced.

Obviously other modifications v1n form,l andl j. 4ov

mounted one above the lother on said'firstnamed member, each of said additional memthe device in displaying any y desired number in the window 12, is obvious. Each of Ithe knobs 23-is rotated independently,

bers having a depending cut-out shoulder `and an upwardly protruding shoulder, thek depending shoulder of each member registering with the upwardly protruding shoulder of,` the member directly below, and means for independently ro- "tating each of said members.

2. A changeable number sign comprising a cylindricalcasing having a window cut-out of the Wallthereof, a floor in said casing, a plurality of multilateral members mounted rotatably one above the other on said floor, the sides of 10 said members 3being .markedi fragments of numbers, the centers of said members being cutout, said members having ring gears on the peripheries of their cut-out centers, and a plurality of shafts rotatably mounted [in said casing each provided with a pinion in mesh with one of said ring gears; each of said members being rotatable independentlyof the others by rotating the shaft having its pinion in mesh with that ring gear.
